23. Classical production of soda by Splvay
method.

24. Diagram of manufacturing process.

25. Example: JSC "Crimean Soda
Plant".

27. Diagram of the Solvay method.

28. Productionwithoutlime.

We found technological
solutions that allow: to eliminate limestone kiln and lime milk preparation
step, to use a new way of ammonium chloride NH4Cl processing; to
eliminate liquid waste from production of 10% calcium chloride CaCl2
solution; to abandon the construction of new and the maintenance of existing
sludge tanks, to additionally produce new marketable product, to generate
additional revenues.

29. Production without carbonation and
ammonization columns.

The new technology
allows to exclude the use of ammonization and carbonation column equipment.
